A fiducial marker includes a fastener and a feedback component to provide a registration signal when engaged by a probe. The feedback component includes light-up cap, a conducting component, a magnetic component and an RFID tag. A cap for registering fiducial markers with robotic surgical systems includes a housing, a socket in the housing for coupling to a fastener, an access port in the housing, a switch disposed in the housing proximate the access port, and a sensory indicator device coupled to the switch, wherein the sensory indicator device produces a signal when activated through the access port to confirm marker contact. Methods of registering a fiducial marker fastener, such as with robotic surgical systems, include manipulating a probe to align with a signal-producing feedback component attached to or integrated with the fastener, and engaging the feedback component with the probe to activate a sensory feedback indicator.

Surgical systems and methods for tracking physical objects near a target site during a surgical procedure are provided, the surgical system employs a navigation system and a surgical instrument; an instrument tracker is provided on the surgical instrument and a patient tracker is provided on the patient's target tissue; the system and method is configured to detect an error condition compromising accuracy of the navigation guidance and to track and monitor a tool-to-bone offset.

Surgical systems, computer-implemented methods, and software programs for generating a milling path for a bone. The implementations involve obtaining a virtual model of the bone, a resection volume defined relative to the virtual model of the bone, and a reference guide defined with respect to the resection volume. Section planes are successively arranged along the reference guide, and each section plane intersects the reference guide and intersects the resection volume. A section path is generated within each section plane and is defined relative to the resection volume. Transition segments are generated to connect section paths of section planes. The milling path is then generated by combining the section paths and the transition segments.

Various surgical systems are disclosed. A surgical system comprises a robotic tool, a robot control system, a surgical instrument, and a surgical hub. The robot control system comprises a control console and a control unit in signal communication with the control console and the robotic tool. The surgical hub comprises a display. The surgical hub is in signal communication with the robot control system. The surgical hub is configured to detect the surgical instrument and represent the surgical instrument on the display.

A position and tracking system for radio-based localization in an operating room, includes a receiver, a mobile cart, a processor, and a memory coupled to the processor. The mobile cart includes a robotic arm and a transmitter in operable communication with the receiver. The memory has instructions stored thereon which, when executed by the processor, cause the system to receive, from the transmitter, a signal including a position of the mobile carts in a 3D space based on the signal communicated by the transmitter and determine a spatial pose of the mobile carts based on the received signal.

A method of assessing inter-device communication pairing in a surgical setting, may include transmitting, by a first intelligent medical device, wireless communication data within the surgical setting, receiving, by a second intelligent medical device, the wireless communication data from the first intelligent medical device, determining, by the second intelligent medical device, communication pairing data indicative of an inter-device communication pairing of the second intelligent medical device with the first intelligent medical device, transmitting, by the second intelligent medical device, the communication pairing data to a modular control tower, and displaying, by the modular control tower on a display device, an augmented reality display comprising one or more virtual objects indicative of the inter-device communication pairing. An interactive surgical system may include multiple intelligent medical devices and displays which can form communication pairs in this manner.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

The disclosure is directed to a novel technique for anatomically orientating a removed tissue specimen with the margins of the tissue from which it has been removed. An example process of marking the margins of the excised surgical specimen and the anatomically adjacent in vivo margins can be implemented by a surgeon at the time of removal of the surgical specimen. After removing the surgical specimen from its adjacent tissue, a surgical cavity is generated. Thereafter, locations around the surface margins of the specimen and appropriate locations on the margins of the surgical cavity are marked with one or more pairs of markers (SpM and IVM respectively) with matching identities.

A medical robot system, including a robot coupled to an effectuator element with the robot configured for controlled movement and positioning. The system may include a transmitter configured to emit signals, and the transmitter is coupled to an instrument coupled to the effectuator element. The system may further include a motor assembly coupled to the robot and a plurality of receivers configured to receive the signals emitted by the transmitter. A control unit is coupled to the motor assembly and the plurality of receivers, and the control unit is configured to supply instruction signals to the motor assembly. The instruction signals can be configured to cause the motor assembly to selectively move the effectuator element and is further configured to (i) calculate a position of the transmitter; (ii) display the position of the at least one transmitter; and (iii) selectively control actuation of the motor assembly.

An apparatus includes a plurality of beads. Each bead of the plurality of beads includes a housing and a magnet positioned within the at least one housing. The apparatus also includes a plurality of interconnection elements. Each interconnection element movably joins together a corresponding pair of beads. Each interconnection element includes a composite material. The plurality of beads and the plurality of interconnection elements are sized and configured to form a loop around an anatomical structure in a patient. The loop formed by the plurality of beads and the plurality of interconnection elements is configured to transition between a constricted configuration and an expanded configuration. The loop in the constricted configuration is configured to prevent fluid flow through the anatomical structure. The loop in the expanded configuration is configured to permit fluid flow through the anatomical structure. The magnets are configured to magnetically bias the loop toward the constricted configuration.
